Detailed Description

Aiming at the drop damage shaft cover phenomenon in the background technology, a great deal of experimental research is carried out in the application, and research discovers that: referring to fig. 9, most of the foldable electronic devices are usually dropped on the ground in the posture of fig. 9, and when the two main body parts of the foldable electronic devices are dropped, the middle frame is excessively deformed by impact and cannot be recovered, the gap between the middle frame and the shaft cover is compressed, so that the folding electronic devices cannot be opened or closed or the opening and closing resistance is increased. And the middle frame can extrude the shaft cover, causes the shaft cover to deform in the folding shaft direction, and when the deformation amount is too large, the shaft cover material yields to generate irreversible damage, so that risks are caused for the reliability of the shaft cover and the structural members connected with the shaft cover.

Based on the research findings, the application further explores and proposes a technical scheme capable of effectively solving the technical problems.

It should be noted that the technical solutions and technical effects are described herein by taking a foldable electronic device as an example, and those skilled in the art should understand that the improvements of the shaft cover and the base structure herein are not limited to the foldable electronic device, but may be applied to other electronic devices.

In this embodiment, the folding electronic apparatus includes a hinge mechanism 300, two main body portions 200, and a flexible screen 100. The two main body parts 200 of the folding electronic device are connected through the rotating shaft mechanism 300, and the two main body parts 200 are rotated relatively by the rotating shaft mechanism 300, thereby realizing folding and unfolding of the folding electronic device. The structures of the two main body portions 200 may or may not be identical, and the specific structures of the two main body portions 200 may be specific to the specific product, which is not specifically limited herein. The main body 200 mainly provides a mounting base and a protection function for the hinge mechanism 300 and the flexible screen 100.

The flexible screen 100 includes a display module and a transparent cover plate, the display module is capable of displaying images, videos, and the like, and the display module may include a touch screen, a light emitting layer, a back plate layer, a substrate layer, and other structural layers. The specific structure of the display module can be selected according to different products. The display module may be a liquid crystal display (liquid crystal display, LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED) or an active-matrix organic light-emitting diode (matrix organic light emitting diode), a flexible light-emitting diode (flex), a mini, a Micro led, a Micro-OLED, a quantum dot light-emitting diode (quantum dot light emitting diodes, QLED), or the like. The transparent cover plate covers the outer side of the display module and plays a role in protecting the display module. The transparent cover plate can be a glass cover plate, and can be other transparent materials with protection function.

Referring to fig. 3, the spindle mechanism in the present application includes a spindle cover 301, a base 302 (also referred to as a "spindle base"), a first swing arm 303, a second swing arm 304, and a connection block 305, wherein one end of the first swing arm 303 and one end of the second swing arm 304 can be rotatably connected to the base 302 or the spindle cover 301, and the other end of the second swing arm is connected to the connection block 305, and specific embodiments of the first swing arm 303 and the second swing arm 304 are provided herein to be rotatably connected to the base 302. The body 200 is connected to the connection block 305, so that when the first swing arm 303 and the second swing arm 304 rotate relative to the base, they can rotate the body 200 connected to the connection block 305, thereby achieving folding and unfolding of the two body 200.

The rotation center positions of the rotation shaft base and one of the swing arms are kept unchanged, and the rotation center positions are used for providing position reference datum; the rotating shaft base can directly set rotation constraint with various swing arms, and can also set rotation constraint with various swing arms through other intermediate parts. The shaft cover 301 is an appearance piece (i.e., an externally visible part) that covers the rotating shaft movement mechanism in a folded state; the shaft cover 301 may cover the rotation shaft movement mechanism together with the middle frame.

The shaft cover 301 is generally located outside the base 302, and one of the shaft covers 301 functions to cover an exterior member (i.e., an externally visible member) of the spindle mechanism in a folded state of the electronic device; the shaft cover 301 may cover the rotation shaft movement mechanism together with the middle frame. For example, the shaft cover 301 can cover the base 302 and other components mounted on the base, so as to improve the appearance and the aesthetic appearance of the foldable electronic device. The sliding movement between the shaft cover 301 and the base 302 can be allowed in the Z direction, and the shaft cover 301 and the base 302 can be rigidly connected by means of locking screws, welding and the like. It should be noted that, in the present application, a direction along the rotation axis is defined as a Y direction, a direction perpendicular to the Y axis and pointing to the flexible screen 100 is defined as a Z direction, a direction perpendicular to a plane defined by the Y direction and the Z direction is defined as an X direction, and each direction is understood with reference to fig. 3.

With further reference to fig. 4-1, fig. 4-2 and fig. 5, in the foldable electronic device of the present application, the base 302 protrudes or is flush with the shaft cover 301, i.e. in the Y direction, the gap a between the base 302 and the middle frame 201 is not greater than the gap B between the shaft cover 301 and the middle frame 201. That is, the distance a between the base 302 and the main body 200 is not greater than the distance B between the shaft cover 301 and the main body 200, that is, the distance a is less than or equal to the distance B, and specific embodiments of which the distance a is less than the distance B are shown in fig. 4-1 to 7.

The folding electronic equipment adopts the design that the base 302 protrudes or is flush with the shaft cover 301 along the Y direction, so that the structural rigidity is improved, the base 302 can effectively bear all or part of impact force, the deformation of the shaft cover 301 and the problem that the flexible screen 100 is impacted are effectively improved, and the anti-falling performance of the whole machine is improved.

In one example, the distance A is approximately in the range of 0.01-0.5mm, the distance B is approximately in the range of 0.01-0.8mm, and the protrusion C of the base 302 from the outer wall of the shaft cover is approximately in the range of 0-0.5mm.

As shown in fig. 4-1 to 7, when the base 302 protrudes from the lid 301 (i.e., C > 0), as understood in conjunction with fig. 8, after the folding electronic device falls in the folded state, when the middle frame 201 of the main body 200 is impacted, the base 302 is pressed against the base 302, and the lid 301 is not pressed against or is pressed against by a reduced force, that is, the base 302 that is contacted with the middle frame 201 first consumes the drop impact force or consumes most of the drop impact force, so that the lid 301 is not contacted with the middle frame 201 at all and is free from the drop impact force or even if the lid 301 is contacted with the middle frame 201, the impact force exerted by the lid 301 is relatively small, thereby effectively improving the deformation of the lid 301 and the impact problem of the flexible screen 100. It should be noted that, after the middle frame 201 is impacted in the Y direction, the base 302 is subjected to positive pressure, the compressive capacity of the material is stronger than the bending resistance, and the material can bear all or part of the impact force, so as to reduce the deformation amount.

When the base 302 is flush with the shaft cover 301 (i.e. c=0), i.e. the end of the base 302 is flush with the outer wall of the shaft cover 301, after the folding electronic device falls down in a folded state, the middle frame 201 is simultaneously extruded to the base 302 and the shaft cover 301 after being impacted, i.e. the falling impact force is jointly borne by the base 302 and the shaft cover 301, the base 302 can effectively share a part of impact force, and compared with the case that the shaft cover 301 alone bears the falling impact force in the prior art, the shaft cover 301 bears only a part of impact force in the example of the application, and the problem that the shaft cover 301 is deformed and the impact flexible screen is caused can be effectively improved.

As will be appreciated with reference to fig. 3 to 5, in a specific example, the edges of the middle frame 201 of the main body 200 near the two ends of the base 302 have vertical walls, the base 302 and the shaft cover 301 are both located inside the vertical walls, and the distance between the base 302 and the vertical walls is not greater than the distance between the shaft cover 301 and the vertical walls. As shown in fig. 3, each of the three sides of the two middle frames 201, except for the adjacent side parallel to the rotation axis direction, has a vertical wall: a first upright wall 2012 extending parallel to the direction of the rotation axis, and two second upright walls 2011 located at two ends of the first upright wall 2012 and extending perpendicular to the direction of the rotation axis, only one second upright wall 2011 is shown in fig. 3, and as will be understood by those skilled in the art in conjunction with fig. 2 and 10, the middle frame 201 also has one second upright wall 2011 located at the other side of the first upright wall 2012. The space surrounded by all the first standing walls 2012 and all the second standing walls 2011 of the two middle frames 201 can be used for installing other parts of the electronic device, and each standing wall can also protect each part.

The second upright 2011 in the above example is closer to the end of the side base 302 than to the shaft cover 301 or is equidistant from both the base 302 and the shaft cover 301.

In a specific example, the middle frame 201 may include a frame near the screen, the frame may be located outside an end of the shaft cover 301, a distance between the base 302 and the middle frame 201 is a distance between the base 302 and the frame, and similarly, a distance between the shaft cover 301 and the frame is a distance between the shaft cover 301 and the middle frame 201. That is, the frame portion forms the second standing wall 2011.

Of course, the middle frame 201 may have a borderless structure.

In order to further improve the deformation condition of the shaft cover 301, the present application further proposes a structural design scheme as shown in fig. 5 and 6, that is, the base 302 is provided with a retaining wall structure 3012, and the retaining wall structure 3012 may be an inclined plane, as shown in fig. 5; of course, the retaining wall structure 3012 may also be a vertical surface, and support the shaft cover 301 in the Y direction. Accordingly, the shaft cover 301 may be provided with an abutment surface 3013 that cooperates with the retaining wall structure, and the abutment surface 3013 may be an inclined surface or a vertical surface. That is, the term "fit" as used herein means that the abutting surface 3013 has substantially the same shape as the retaining wall structure 3012, that is, when the retaining wall structure is a vertical surface, the abutting surface 3013 of the shaft cover is also a vertical surface, the two vertical surfaces are disposed opposite to each other, when the retaining wall structure 3012 is an inclined surface having an angle with the Y direction, the abutting surface 3013 is also an inclined surface, and the retaining wall structure 3012 is substantially parallel to the abutting surface 3013, so that both have a predetermined distance in the Y direction and the Z direction. Here, the vertical plane is a plane parallel to the Z direction, and reference is made to fig. 6. In this way, even if the shaft cover 301 receives a partial impact force, the deformation amount is reduced due to the support of the retaining wall structure of the base 302. Retaining wall structure 3012 includes, but is not limited to, vertical retaining walls or beveled retaining walls as shown in fig. 5 and 6, and any structure that provides support in the Y-direction is within the scope of the present application. The clearance E between the retaining wall structure of the shaft cover 301 and the base 302 in the Y direction in the folded state is 0-0.3mm. In addition, in the folded state, a gap can be formed between the retaining wall structure and the shaft cover 301 in the Z direction, and the gap range is 0-0.4mm.

Further, a clearance may be provided between the protruding portion of the base 302 and the shaft cover 301 in the Z direction, and the clearance may be approximately 0 to 0.4mm.

In a specific example, a guide member 306 is further mounted on the shaft cover 301 of the rotation shaft mechanism for guiding the bending portion of the flexible screen 100 to be folded and deformed. The guide member may be a T-block, although other configurations are possible. Referring to fig. 4-1, 4-2 and 7, the guide member 306 is generally mounted on the shaft cover 301, and the shaft cover 301 may be provided with a mounting hole 3021, and a part of the structure of the guide member 306 is mounted on the mounting hole 3021. To further reduce the swing amplitude of the structural member of the guide member 306 caused by a drop, and reduce the risk of the structural member of the guide member 306 striking the flexible screen, the present application further proposes a structural design as shown in fig. 7. The Y-direction gap between the base 302 and the guide member attached to the cover is very small, and the distance F between the two is approximately 0-0.20mm, which has the advantage that the shaking amplitude of the guide member 306 caused by the impact on the ground after the mobile phone falls is greatly reduced due to the interception of the support of the base 302, so that the risk that the structural member of the guide member 306 impacts the flexible screen 100 is reduced.

It should be emphasized that although only a size range is given above, other specific values within the size range are not listed, and those skilled in the art will appreciate that the size ranges described herein are all values within this range, including the boundary values, e.g., the protrusion of the protrusion from the outer wall of the shaft cover ranges from 0 to 0.5mm, and that the protrusion of the protrusion from the outer wall of the shaft cover may be any value between 0 and 0.5mm, including the boundary values 0 and 0.5mm. Likewise, other numerical ranges are not explained herein.

To accommodate the placement of the guide members, the protrusions 3022 on the base 302 may be separated on either side of the folding axis of the flexible screen 100 to avoid the installation space for the guide members. That is, the base includes a body 3023, and two protrusions 3022 are extended outwardly from a partial end of the body 3023 with a predetermined distance between the two protrusions 3022.

The number of the protrusions 3022 may be one, two, or more. Fig. 4-1 and 4-2 show examples in which two protrusions 3022 are provided.

Other structures of the foldable electronic device may refer to the prior art, and are not described herein.

Specific examples are set forth herein to illustrate the principles and embodiments of the present application, and the description of the examples above is only intended to assist in understanding the methods of the present application and their core ideas. It should be noted that it would be obvious to those skilled in the art that various improvements and modifications can be made to the present application without departing from the principles of the present application, and such improvements and modifications fall within the scope of the claims of the present application.
